GPL License Query on a Plain Linux Application

GPL License Query on a Plain Linux Application

[Ramya Desai]

Dear All,

I have written an application where it uses plain system calls like
open, read, write etc. and runs in the user space. My question here,
is this application comes under GPL?

Any ideas / hints would be appreciated.

Thanks.

Regards,
Ramya.

you might want to ask FSF.org for that. But bottomline is that if you're
not linking with any GPL code, you don't have to be GPL if you don't
want to, although there are many benefits of doing so (IMHO).

This is a technical not a legal list - I would ask the Linux Foundation
if you want a legal answer.

In general though your question seems really to be "is my application a
derivative work of the kernel". That would be a surprising interpretation
(speaking as a non-lawyer) but also one the community wanted to be sure
never occurred. Hence the COPYING file for the kernel itself states:

   NOTE! This copyright does *not* cover user programs that use kernel
 services by normal system calls - this is merely considered normal use
 of the kernel, and does *not* fall under the heading of "derived work".
 Also note that the GPL below is copyrighted by the Free Software
 Foundation, but the instance of code that it refers to (the Linux
 kernel) is copyrighted by me and others who actually wrote it.
